SPECIFICATION forming part of Letters Patent No. 336,378, dated February16,1886. Application filed October 24, 1885. Serial No. 180,847. (Nomodel.)

To all whom it may concern: The letter A designates an outer doubleBeitknown thatLORsoNWV.Bnxxnrnaciti walled vessel, made of copper orother non zen of the United States, residing at Washingcorrosivematerial. This vessel is preferably ton, in the District of Columbia,have invented of cylindrical form, and is provided between certain newand useful Improvements in Autoits walls with a packing of any suitablemamatic GasGenera'tors; and Ido hereby declare terial or materialsforming a good non-conthe following to be a full, clear, and exactdeductor of heat.

The two pipes e andf are made to communicatethrough a short pipe, h, which is also fitted with a suitable stop-cock.The upper end of the hydrocarbon-chamber is provided with two openings,fitted with short tubes '6 and i, each of which is provided withstop-cocks. One of these tubes is the supply-tube, or that through whichhydrocarbon oil is supplied to the reservoir, and the other an outletfor the escape of air or gas as the oil is supplied to the reservoir.The feedpipe i, as shown, is fitted with a strainer, 2", to catchimpurities or particles of matter which should not go into thereservoir. A wall, j, connected by a liquid-tightjoint to the top of thevessel A, surrounds the space including these tubes i and i and theupper end of the central well, B, and into the space thus surroundedwater or other suitable air or gas sealing liquid is poured until itsubmerges the said tubes and upper end of the well B, after whichanother cover, E, provided with a vent, 6 adapted to be opened andclosed by any suitable meansas, for example, a screw-plugis placed overthe parts. The vent e permits the escape of air which may be within thecover when the same is placed into the water over the tubes 1, i, and B,before mentioned. This construction renders the admission of air to orthe escape of gas from the vessel impossible. The opening to the spaceinclosed by the-wallj may be closed by means of hinged cover F, providedwith a suitable looking or fastening device.

In order that the residuum in the upper chambers of the apparatus may beremoved, I provide each of the chambers 1 and2 with valved openings 70.The stems of the valves in the openings have their operatingleversconnected to rodsl Z. The levers for operating these valves are soarranged that their weight, together with that of the rodsl Z, will tendto hold the valves so that the openings will be cldsed, and are onlyopened by the lifting or raising of the rods 1 7,. This opening by thevalves will allow all the residuum in the generating-chambers to flowdown to the lower one or to the bottom of the vessel, from whence theresiduum may be pumped or otherwise removed therefrom through thewell-tube B.

The openings 70 may also be provided with a wire-gauze or similarcovering.

The several generatingchambers may be filled with asbestus fiber,excelsior, or other absorbent material to be saturated with thehydrocarbon oil.

The operation of the gas-generator, constructed as herein shown anddescribed, will be as follows: When the reservoir or chamber 0 issupplied with oil,it will flow through the out let 0 until the chamber 1is supplied to alevel with the upper end of the tube 1), through whichit will flow to the next, and so on tothe last chamber,3. The oil flowsinto the chamber 3 until the float is raised sufficiently to cause thevalve in the outlet 0 to close said outlet. The height to which thefloat shall be raised will be determined by the depth of oil desired inthe lower chamber, and for this purpose the upper end of the rod d ismade with aseries of holes, through which a pin or other device may bepassed to secure it to the lever d. The oil, as before described, ispoured through the cook or tube 1', and this, of course, before thewater is supplied to seal the joints. The air or gas coming through thepipe e may be made to pass first into chamber 3, through which it willpass over the surface ofthe oil and through the saturated absorbent byacircuitous route to the lower end of the tube B, on the other side ofthe partition a, which separates the inlet portion of the chamber fromthe outlet. This partition, being a complete one, compels the air or gasto take a circuitous route in order to pass to the next chamber. In thechamber 2 the same operation takes place, excepting that the gas flowsin the opposite direction. Thejgenerated gas or airfinally reaches themouth of the outlet-pipe f, when it is ready for use. WVhen it isdesired that the air or gas be not so highly charged,the branch pipe 6is closed and the pipe 6 opened; or the air orgas may be admitted to theapparatus through both the branches or through the lower one only.

It will be seen that the supply of oil to the severalgenerating-chambers is automatically regulated, and that the apparatuswill need no further handling after the reservoir is once filled untilthe supply therein is exhausted.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1.

2. A gas generator, substantially as described, comprising the vessel A,having the central well with automatic oil-supply-regulating deviceslocated therein, and its upper portion constituting the oil-reservoirand its lower portion constituting the generator, divided by partitionsinto horizontal chambers or compartments, the tubes b in saidpartitions, extending above and below the same, the vertical walls at,extending from top to bottom of the chambers or compartments, and fromthe wall of the well B to the wall of the vessel A, provided withopenings occurring alternately at the walls of the well and vessel, forthe purposes described, the solid portion a in said compartment, aninlet upon one side and an outlet upon the other, and pipes leading toand from said compartments outside of the vessel and central well,substantially as shown and described.
